So right now my car is in pieces, i have my head out of the engine bay and practically every sensor in the engine bay is disconnected

Today i was trying to drain my gas tank so i thought i'd let the fuel pump do the work by priming it and let the fuel feed line go into a canister

so as i turned my iginition to ON, nothing happened... so i glanced over to my pfc and noticed the hand controller wasnt coming on

So what could be the cause of this? does it have a fail safe to not turn on if a specific sensor is disconnected? Could i have blown a fuse or something???

wierd thing is, this whole time, my battery wasnt even connected, so i really doubt it could be fried

someone please put my heart to rest!! i havent even gotten the chance to try it out yet!

How much power left in the battery? Most ECUs require at least about 7V before they will spring into life.

i'm not sure, i dont have a multimeter but i had it hooked up to my charger, and i'm currently charging it up.

it's a faily new optima redtop so it shouldnt be dead...

i'll try it again after a few hours of charging

Got any lights on the instrument panel when u turned the IGN on???

U can also check for horn, headlights etc. ....if not ur batt is dead.

all the lights come on, didnt check the horn etc though

BUT i just moved the battery to another car and it started right up

i also connected another battery to my car.... same thing, hand controller doesnt boot up...

man if this thing got somehow fried i'm going to blow up!!!

well common sense would prevail here, given you have pulled the whole car apart and all the sensors etc

it could be anything, check the basics, double check everything, trace everything, and use elimination

how on earth do you expect guys on a forum to help? if the car is in bits / sensors unplugged?

it could be one single wire causing it to not power on

well i just wanted to know if anyone knew for a fact that unplugged sensors would cause the pfc to not turn on

    • Hang on. Let me get this straight. The desire is to have coilovers, BC in particular, to be MORE comfortable on Sydney roads than stock suspension? Well, that's obviously not right. BCs have crude damping design at the very best, and typically hard spring rates. BC stands for Billy Cart. And then, the desire is to put in some shitty old worn out stockers, to get it blue slipped and then put the BCs back in? And then.....what? Not worry about getting pulled up by the Plod? Because you seem to have raised a worry about paying for engineering (which actually does solve all your legality problems) and still getting pulled up.... but the only problem there is that if/when that happens you have to show your paperwork at the inspection station. Whereas, if you just swap in borrowed shitty old stockers to get it slipped now, and then you get defected in the future, you have to go find more shitty old stockers then too. You course of action looks like this set of options: Buy brand new stock type dampers, and springs. probably cost a bit more than $1k all up, but will last for the remaining life of the car. Put them in, pass inspection, drive on them forever more. Hell, they could even be really nice Bilsteins and Kings or other lower&stiffer springs if you wanted. Get the car engineered as is. ~$1k. Buy new Shockworks coilvers (or MCA) and also pay for engineering. You're spending a lot more here. But these will be the best things that you could drive around on.
    • Might be worthwhile hitting up Facebook's groups, I know most of them contain terrible people and scammers - however you might be able to find someone that's in Sydney with factory suspension you could purchase and/or hire. Just do not send any form of money anywhere, in person cash only.
    • Thanks @Duncan Ride height is fine. I think it's almost stock tbh. Happy to share a pic. I don't actually have a regular mechanic as haven't lived in Sydney too long. Could you or anyone recommend any shops in Sydney?
    • You just need a different blue slip shop (preferably one you regularly use as a mechanic), and make sure the coil overs are as close as possible to standard height
    • yeah the sugar refining companies were pushing for the same in Oz originally, all fuels were going to have 10% ethanol to make them "cheaper" (noting, that the loss in l/100 might be greater than the decrease in price). I guess they won that fight in Canadia
